My invention has relation' to chair-frames and4 It consists in the construction of a strong and durable chair-frame, by the combination of certain strips of bent wood in such a manner that they shall rein- `forceeach other, as hereinafter described.

V@he letter'A of the drawing represents a strip of wood having its grain running parallel to the surface, which, after being properly steamed, is bent into the requisite shape to form the two back posts, the side rails, and the front rail of the seat frame.'

The ends of this bent piece of wood, which fornr the back posts, are connected at their upper, middle, and lower portions, respectively, by the top slat, middle slat, and 'back' rail.

B B represent pieces of Wood, similarly steamed, and bent into shape to 'form the front andrear legs of the chair. Y ,v t

Each piece forms a front and rear leg, and extends along under the side rail of the chair-seat frame, to

which it may be attached by screws or in any other suitable manner. l

G 0 designate strips of straight-grained wood, bent to'suit the curves ot' the rear faces of the back-posts and of the rearlegs.

Euch strip Gis fastened securely by screws and glue, or in any other suitable manner, to the leg and back-post, on the same side of the chair-frame, connecting the two,'strengthening them, and serving aS lan etlcieutv brace to keep them in position; and in this connection it may be observed that the back .l

posts and rear legs of a chair-frame are usually subjected to greater strain than the other portions.
